WebbSo I'm writing a program that takes as input a message, and produces the encoded version of that message using Hadamard encoding. Then another program takes the encoded message, and produces the original message. WebbThe Hadamard transform can be defined in two ways: recursively, or by using the binary ( base -2) representation of the indices n and k . Recursively, we define the 1 × 1 Hadamard transform H0 by the identity H0 = 1, and then define Hm for m > 0 by: where the 1/ √ 2 is a normalization that is sometimes omitted. For m > 1, we can also define Hm by:
